How do I extend the access of a link to a project for friends? So that they can always watch the code

Can I share a project with friends only with a generated link? My friends saw the code too.
The problem is that the generated parcel is processed after 60 days, so after 60 days you need to generate a new messenger? Is it possible to make it always available?

Nope, not possible unless you publish the project as a web app which requires a paid subscription with Thunkable.

You can share a project page link. That’s always up to date.

You have two ways to share the link.

When you use the share menu option, you get a link that will be available for 60 days. But when you use the URL of the Design screen of your project then it will be available all the time.
